The present research aims to extend the literature on the effects of interpersonal political disagreement on political expression on social media. It investigates how disagreement-motivated information repertoire filtration and discussion network heterogeneity play a role in the disagreement–expression nexus. A two-wave online panel survey (n = 791) implemented in Hong Kong finds that encountering disagreement during political conversations is associated with filtering the information repertoire. While information repertoire filtration itself may not lead to political expression, political disagreement influenced political expression via information repertoire filtration, and this effect was stronger when network heterogeneity was low. The result indicates that politically motivated selectivity makes already-homogeneous online networks even more fragmented. The present study enriches the literature regarding how digitally mediated disconnectivity creates a personalized, homogeneous private sphere during interpersonal political communication, which may fail to nurture an open and inclusive society.
